SAFCII Problems!!! Need Help ASAP.

My friend and I installed my SafcII on my stock ka24e about 1 hour ago.
When we started it, it did the usuall sputter so we changed the fuel maps, now it idols fine(ish).
But the biggest problem is when i hit about 2300 rpm it sounds like I am bouncing the limiter…Brum Brum Brum Brum until i let off.
I can downshit to make it go past 2500 but when i give it gas it does nothing, until it comes down to 2300 ish then it hits the limiter.

Does anyone know how to fix this problem or have a clue what it is?
I am running pretty rich at the moment, reason being we tuned it for about 1 min just so it wouldnt stall of idoling.

I also need a wideband A/F sensor.
Anyone have an idea of where i can get one?

Thanks for any help!
